Discovery of Ancient Stem Cells in Sea Anemones Offers Clues to Immortality and Regeneration

The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists led by Ulrich Technau from the University of Vienna have now identified possible candidates for multipotent stem cells in the sea anemone for the first time.

Breakthrough Research Reveals Early Development of Eye Macrophages in Mice

Macrophages, also known as scavenger cells, are part of our immune system. They destroy invading pathogens and are found in the organs and the bloodstream.

Plant-Based Diet Slows Down Biological Aging Markers

Eating a vegan diet for eight weeks is associated with reductions in biological age estimations based on levels of DNA methylation -; a type of chemical modification of DNA (known as an epigenetic modification) that alters gene expression but not DNA itself. Previous research has reported that increased DNA methylation levels are associated with aging. The findings, which are based on a small randomized controlled trial of 21 pairs of adult identical twins, are published in BMC Medicine.

UCL Study Uncovers Astrocytes' Role in Brain Energy Boosting Mechanism

A key mechanism which detects when the brain needs an additional energy boost to support its activity has been identified in a study in mice and cells led by UCL scientists.

Unlocking the Secrets of Aging Brains

Researchers have determined the potential mechanisms through which some long-lived mutants of the Caenorhabditis elegans model system experience cognitive decline and others can retain learning and memory into old age.

Genetic Influences on Lifespan Variance and Healthspan in Caenorhabditis elegans

Why do some people live for longer than others? The genes in our DNA sequence are important, helping avoid disease or maintain general health, but differences in our genome sequence alone explain less than 30% of the natural variance of human life expectancy.

Epigenetic Changes in Insulin-Producing Cells Linked to Type 2 Diabetes Onset

Do epigenetic changes cause type 2 diabetes, or do the changes occur only after a person has become ill? A new study by researchers at Lund University provides increased support for the idea that epigenetic changes can cause type 2 diabetes.
